but it's a bit culture specific. German children TV has a pretty long running show that does "how it's made" for children + small, probably only 5 minute animated stuff and at the end a puppet/animated show of this old bear telling his grandchildren weird made up stories that he claims are totally true.
Obviously this is feature length. So in this movie, his old archrival shows up, and kidnaps the kids. Grandpa has to roll up his sleeves, and go save them. And of course do wild stuff that sounds totally made up when he tries to tell the kids later.
“The young and fanatical Jon is appointed pastor to a remote church in 17th century Iceland. As is custom, he marries the widow of his predecessor, a woman much older than he is. He is ardent in his fight against Satan, and the villagers don't dare to question his authority. When he falls for a beautiful young woman, Jon is convinced witchcraft is at work, and his crusade leads to cruel executions of innocent people. The stronger his lust, the deeper his madness drives him in his religious fervor.”
"Gentlemen of Fortune" is a hilarious movie where a school principle is chosen to infiltrate a band of crooks due to him looking exactly like their boss.
Fanny and Alexander. Also Bergman, also a masterpiece. Period dram about two siblingsa, is available both as a movie and a mini series, the mini series is of course longer, but the version I recommend, since it's easier to take breaks, it's awesome, but it's pretty dark
